OpenAI’s Decisions API returns typed answers for classification and routing

developers.openai.com 7 min read Editor score 7/10

The public-beta API evaluates text or images and returns typed answers, such as a choice or rubric score; OpenAI says it is about ten times faster than the Responses API. It offers a specialized endpoint for applications that classify, route, or prioritize requests.

What: - The Decisions API is a public-beta endpoint that evaluates text, images, or both and returns typed predicate, choice, or score answers.
How: - Requests include a model, shared input, and typed questions; responses return named answers with probabilities or scores.
Why it matters: - Typed outputs support content classification, request routing, and prioritization; Structured Outputs remains an option for custom-schema generation.

The Decisions API takes a model, input, and questions, then returns an answers array. Sketched from the article's own text.
